Objective To compare the effect of traditional operation and small arc incision with low collar in thyroidectomy, and to explore the effective operation for this disease. Methods Eighty-six patients with thyroid surgery admitted to Puren Hospital of Wuhan City from October 2017 to October 2018 were divided into traditional group and minimally invasive group, with 43 cases in each group. The traditional group was treated by traditional operation, while the minimally invasive group by low-collar small arc incision. The two groups were compared in intraoperative conditions (operation time, bleeding volume, incision) , incision length, postoperative condition (degree of pain, length of hospital stay), parathyroid hormone and serum calcium level, complications (incision subcutaneous nodules, incision adhesion, hypocalcemia, hypothyroidism, recurrent laryngeal nerve injury), and incision aesthetic level. Results The operation time, bleeding volume and incision length of the minimally invasive group were less than those of the traditional group, and the pain score and hospitalization time of the minimally invasive group were smaller than those of the traditional group (t=18.963, 15.843, 3.350, 18.943, 3.443, all P<0.05). The levels of parathyroid hormone and serum calcium in the two groups were lower than those before operation, but the minimally invasive group decreased less (t=4.310、13.160; both P<0.05). The incidence of complications in the minimally invasive group (9.3%) was lower than that in the traditional group (27.8%) and the difference was significant (χ2=4.914, P<0.05); the aesthetic degree of incision in the minimally invasive group was better than that in the traditional group (χ2=12.797, P=0.002). Conclusions The application effect of low collar small arc incision in thyroidectomy is remarkable, which has the advantages of shorter operation time, less bleeding, smaller incision length, slighter postoperative pain, shorter hospitalization time and fewer complications. It also has less influence on parathyroid hormone and serum calcium levels, good postoperation course, and worthy of clinical implementation.
